100% On-chain NFTs (image 'n' metadata)

MetaHacker

This is 100% (images + metadata) on-chain NFTs. Unique soldier called MetaHacker which pairs up as teams to win cards combination game.

Illustration

MetaHackers representations and layers of svg traits used in this project have been designed by the artist RingoCoco.

The challenge

Creating a DApp which computes and stores on-chain 35 ko (avg.) svg images + metadata.
Some +50 ko images have passed the tests.

The solution

• ✅ Upload and mapping of the Genes with variations as svgs -on-chain- + Skills | MetaHackerBase,
• ✅ Creating -on-chain- a unique MetaHacker NFT | MetaHackerFactory,
  • ✅ request a random uint256 number from ChainLink,
  • ✅ random uint256 number is read at bits level > walker's alias method computes genes' variations > unique traits combinations is hashed and checked. MetaHackerEngineDown,
  • ✅ from Genes with variations mapping, generation and encoding of svg image, MetaHackerEngineDown,
  • ✅ from Genes with variations mapping, generation of image metadata (OpenSea compliances), MetaHackerMetadata,
  • ✅ encoding of URI as data URL, MetaHackerMotorFactory,
• ✅ Storing -on-chain- the MetaHacker's data URL as transaction ID (as input data in bytes format this needs off-chain convertion of data URL as bytes),MetaHackerMotorFactory,
• ✅ Storing -on-chain- data URL shortened via tokenURI() (OpenSea compliances), MetaHackerMotorFactory,
• ⭕ To Do developments 🚧
  • -on-chain-
    • Adding 'Polygon Basic Integration and Meta-transactions' OpenSea compliances into MetaHackerFactory,
  • -off-chain-
    • Front-End + Netifly building,
    • A custom MetaHacker's data URL shortened as for eg.: https//www.metahacker.com/metadata/00 (OpenSea compliances),

string dataURLhash

• traithash: 256 bit hash of the struct (each, 8-bits, slot is a gene which can store a variation of value up to 255), see.: Trait Hash Bitmasking
• dataURLhash: transaction id that contains dataURL as input data under bytes format.
